Best Mix for Pumped Concrete | JLC Online

Mar 01, 2010 · Generally speaking, the maximum slump for a pumped mix is about 6 inches. The ideal concrete mix for pumping typically contains air-entraining agents, a little extra sand (compared with a standard concrete mix), often some fly ash, and a well-graded aggregate blend. To make the concrete easier to pump and place as it comes out of the hose, many

Why Pump Concrete? | Construction Equipment

Sep 28, 2010 · A concrete pump places concrete faster and more accurately with less labor than any other method. A job that would take five men two and a half hours to pour would only take three men one hour to pump. Contractors who pump concrete consistently report labor savings of 50 percent compared to truck dumping.

CONCRETE 101

Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good average slump for pumping.
